[REBOL] Re: financial functions

Hi,
> << Does anyone have an internal rate of return function? >>
I use financial functions off and on - mostly in Excel, but I aim to reduce
my use of that tool if I can.
So I went a bit wild and created some functions too.
NPV - Net present value of periodic cash flows.
DCF - Discounted cash flow where the cash flows are on specific dates.
IRR - Internal Rate of Return using NPV or a DCF function.
SOLVE - The thing that IRR uses. Performs secant iteration to solve
a function. Could potentially be used for Goal Seek functionality.
